In these proceedings we highlight the main results about dark matter (DM) search in dwarf irregular galaxies with the \textit{Fermi} Large Area Telescope. We analyze 11 years of Fermi-LAT data corresponding to the sky regions of 7 dwarf irregular (dIrr) galaxies. DIrrs are DM dominated systems, recently proposed as interesting targets for the indirect search of DM with gamma-rays. We create a spatial template of the expected DM-induced gamma-ray signal with the CLUMPY code, to be used in the analysis of \textit{Fermi}-LAT data. No significant emission is detected from any of the targets in our sample. Thus, we compute the upper limits on the DM annihilation cross-section versus mass parameter space. The strongest constraints are obtained for $b\bar{b}$ and are at the level of $\langle\sigma v \rangle \sim 7 \times 10^{-26}\text{cm}^{3}\text{s}^{-1}$ at $m_\chi\sim 6$ GeV.
